Now for an update on the salvage of the Iranian tanker which sank off the coast of Shanghai.

The Ministry of Transport says the location of the Sanchi has been determined. The Shanghai Salvage Bureau will send a robot sub down. Tuesday's satellite remote sensing data showed the oil pollution concentration areas have expanded to 69 square kilometers. Oil can also be seen sporadically in around 40 square kilometers of sea area. Authorities say the next stage of work will focus on cleaning up the oil.
